Objective To investigate the effect of tetrandrine(Tet) on the expression of bax,bcl-2,and transforming growth factor-β2(TGF-β2) mRNA in cultured human fibroblasts of Tenon's capsules(TCFS) and explore its possible mechanism.Methods The third passage of TCFS cultured in vitro were exposed to 1×10-5 mol/L Tet for 24 h,and real-time fluorescence quantitative PCR was used to detect the changes in the expressions of bax,bcl-2,and TGF-β2 mRNA.Results The expression level of bax mRNA was obviously higher,while bc...
